[0002] The packing bag is the bag for packing various articles, and the goods are conveniently transported and easily stored in the production flow process. It is widely used in daily life and industrial production.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0028] Please refer to Figures 1-3The utility model provides a technical scheme: a send rope mechanism for full -automatic rope -threading machine of packing bag, including base 1, install two disc frame 2 of right side of base 1 upper end, the rope -off disc 3 of detachable installation between two disc frame 2 upper end, install drive motor 6 of left side of base 1 upper end, install first rope -threading disc 601 of drive motor 6 upper end and rotate and install second rope -threading disc 7 of left side of base 1 upper end and with first rope -threading disc 601 mutually consistent, be provided with the damping mechanism of reducing the inertia rotation of rope -off disc 3 after the stress of rope -off disc 3 between disc frame 2 and rope -off disc 3.

[0029] Specifically, as shown in Figure 1 and Figure 2 The damping mechanism includes an inner screw ring 201 fixed on the disc frame 2, a guide sliding cylinder 202 installed on the outer part of the inner screw ring 201 through screwing, a guide sliding column 4 movably installed on the inner side of the guide sliding cylinder 202, a ball 401 fixed on the inner end of the guide sliding column 4 and abutting against the rope-off disc 3, and a spiral extrusion spring 402 sleeved on the outer part of the guide sliding column 4 and located between the guide sliding cylinder 202 and the ball 401. Under normal circumstances, under the action of the elastic force of the spiral extrusion spring 402, the ball 401 can continuously elastically abut against the outer wall of the rope-off disc 3, thereby increasing the motion damping feeling of the rope-off disc 3 and reducing the occurrence of abnormal problems such as relaxation, winding, knotting and line explosion during the rope feeding process.

[0030] The outer part of the rope-off disc 3 is provided with a plurality of concave ball grooves 301 corresponding to the positions of the ball 401, which can improve the motion damping of the ball 401 on the surface of the rope-off disc 3. When the movement speed of the rope-off disc 3 is slow, the ball 401 can stably pop into the concave ball groove 301, thereby increasing the damping feeling of the rope-off disc 3 when rotating at low speed. When the movement speed of the rope-off disc 3 is fast, the ball 401 can jump over the concave ball groove 301, thereby reducing the damping feeling of the rope-off disc 3 when rotating at high speed.

[0031] The outer end of the guide sliding column 4 is detachably provided with a limiting lock block 5 vertically penetrating the guide sliding column 4, and the outer end of the guide sliding column 4 is provided with a lock groove 403 matched with the limiting lock block 5. After the limiting lock block 5 is inserted into the lock groove 403, the overall movement of the guide sliding column 4 in the direction of the rope-off disc 3 can be limited, thereby preventing the ball 401 from accidentally detaching or sliding out of the guide sliding cylinder 202 under the action of the spiral extrusion spring 402 or other forces, and ensuring the stability of the guide sliding column 4 installed in the guide sliding cylinder 202.

[0032] Specifically, as shown in Figure 1 and Figure 2 The left and right sides of the base 1 located between the first rope-threading disc 601 and the second rope-threading disc 7 are respectively fixedly connected with a second rope-threading frame 103 and a first rope-threading frame 102, and a linkage part for synchronous and stable rotation of the first rope-threading disc 601 and the second rope-threading disc 7 is arranged between the first rope-threading frame 102 and the second rope-threading frame 103.

[0033] The linkage part comprises a support frame 8 installed between the upper ends of the first rope passing frame 102 and the second rope passing frame 103, a second pulley 801 rotatably installed in the middle of the support frame 8, a plurality of tooth blocks 802 fixed in an annular array in the middle of the second pulley 801, a driving gear 602 installed on the upper end of the first rope pressing disc 601 and engaged with the plurality of tooth blocks 802, a first pulley 701 installed on the upper end of the second rope pressing disc 7, and a transmission belt 9 installed between the first pulley 701 and the second pulley 801. When the driving motor 6 drives the first rope pressing disc 601 to rotate counterclockwise, the second rope pressing disc 7 can rotate clockwise at the same speed under the synchronous transmission of the driving gear 602, the second pulley 801, the first pulley 701 and the transmission belt 9, so as to stably convey the rope horizontally to the left between the first rope passing frame 102 and the second rope passing frame 103.

[0034] Specifically, as shown in Figure 1 and Figure 2 , the upper end of the base 1 is provided with a mounting hole 101 at each of the four corners, so that the base 1 can be fixed and installed on the rope feeding station of the full-automatic rope passing machine of the packaging bag through fasteners.

[0035] Working principle: when in use, the rope feeding mechanism can be installed and fixed on the rope feeding station of the full-automatic rope passing machine of the packaging bag through fasteners, and then the control circuit of the rope feeding mechanism is connected to the control terminal of the full-automatic rope passing machine of the packaging bag, so as to complete the assembly operation between the rope feeding mechanism and the full-automatic rope passing machine of the packaging bag. In actual use, the rope reel 3 with the wound rope is vertically and downwardly buckled between the two disc frames 2, and then the rope on the rope reel 3 is pulled through the first rope passing frame 102 and put into the first rope pressing disc 601 and the second rope pressing disc 7, and finally pulled out through the second rope passing frame 103. When the driving motor 6 is powered, the driving motor 6 can drive the first rope pressing disc 601 to rotate counterclockwise, and under the synchronous transmission of the driving gear 602, the second pulley 801, the first pulley 701 and the transmission belt 9, the second rope pressing disc 7 can rotate clockwise, so as to continuously convey the rope on the rope reel 3 from right to left. In the process of rotation of the rope reel 3, under the action of the elastic force 402 of the spiral compression spring, the ball 401 on the guide slide column 4 can elastically abut against the outer wall of the rope reel 3, so as to increase the damping feeling of the rotation of the rope reel 3. At the same time, the ball 401 can reciprocatingly and elastically buckle between the plurality of inner recessed ball grooves 301 of the rope reel 3. The faster the rotation speed of the rope reel 3, the smaller the motion damping feeling, and the slower the rotation speed of the rope reel 3, the larger the motion damping. Therefore, the dynamic damping operation of the rope reel 3 is realized.

[0036] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
